John Stevens was a man with a purpose. He was one of the few who knew what was going to happen today, but the only one who was prepared to do anything about it. London was surprisingly empty today, he mused, as he drove through the streets as fast as possible without arousing suspicion. He could not afford to be delayed. One quick glance at his watch confirmed what he thought: he had only 38 minutes left, easily enough time to do what he intended, but maybe not enough to get away cleanly. Damn. But maybe, he thought, the public need some martyrs to see what was going on.

A speck of blue appeared on the road and vanished just as quickly. Odd, he thought, as it flashed again, from no discernable source. He maintained his speed. A third flash of blue blinded him for less than a second, but as his vision recovered, a blue box appeared in front of him. He cursed loudly and floored the brake, which slowed him down, but not enough to avoid crashing.

The Tardis shook momentarily throwing its occupants around. The Doctor grabbed the console, pulling himself up. "Everyone, we've landed!" he announced.

"It doesn't normally shake like that" observed Rory, rising, holding his head.

"Well, no. But it's not the Tardis. More likely is that something must have collided with it shortly after landing. You see, not only does the Tardis expertly disguise itself to blend into its surroundings" Amy and Rory exchanged looks, "Well it would, but that's not the point. It also chooses somewhere remote to avoid stuff like this that could avoid altering history; problem is that she's quite an old thing, probably had quite a lot on the milometer before I borrowed her. Bound to happen eventually."

"So, just to be sure, what happened?" asked Amy.

"Let's find out, shall we?" The Doctor smiled before running out the doors. Amy and Rory followed to be greeted by the sight of a crashed car. The Tardis, they noticed remained unharmed. The doctor was helping a man out of the wreckage.

"What the hell is that thing? Look, never mind, I've only got… 36 minutes to get to parliament. Now if you'll excuse me" the man reached into his car.

"Quite frankly I don't think I should excuse you. You just drove into my nice antique novelty phone box. Well, probably antique…ish. Listen, what year…" He paused as the man withdrew a rifle from what remained of his car and pointed it at them.

"Out of my way" he snarled, making motions with his gun.

"Now that's odd" said the Doctor, who was ignoring the man or totally oblivious to the situation. "That's not your standard issue gun. It looks fairly light and…plastic, maybe. Oh! Oh! I see, it's camoflax!" He looked at Amy and Rory and continued explaining; "it's a special polymer that conceals metal parts so that you can take it through a metal detector" he turned back to the man, "why take a gun to parliament?"

The man advanced, gun still raised. "Move or gingey here gets her brains blown out!" he snarled. He took two steps forward before groaning and falling to the ground.

"No-one messes with my wife!" yelled Rory, perhaps a bit loudly.

"Do calm down, Rory, I was going to move. I think this centurion stuff is going to your head a bit." muttered the Doctor.

"I thought it was very brave of you," said Amy, kissing him on the cheek.

"Well, yeah." replied Rory modestly.

"Now who do we have here?" Asked the Doctor; bending down to pick the unconscious man's pockets. "A, a wallet and an ID card; belonging to a Mr John Stevens MP. Oh, and a driving license issued in 2123. So assuming this man's around 40…"

"55 actually," interjected Rory. "His ID card says his date of birth and age on it so it's 2161. Must you do everything the hard way?"

"It's more fun to guess; either you're right or you're pleasantly surprised; you win both ways."

"Now the question is; why would he take a gun to parliament?"

"Good question, Amy, in 2161, the president would be…"

"President?"

"Yes, president. You don't think the royals would carry on forever did you? But don't worry, there's a civil war in 2358 and King Bob the first is put on the throne."

"King Bob?"

"The first. I know it's amusing, but I'm afraid not relevant to the moment at hand. Don't interrupt me when I'm astounding you with my knowledge of Earth history, please." He sighed.

"We're sorry. Continue."

"As I was saying, 2161, President Green… See, not nearly as impressive now is it? But why? He was generally quite well regarded, apart from some rumours of him going a wee bit mad near the end."

"How wee?" Asked Amy.

"Some people say he wanted to declare war on France, but that was never proved because…Oh…"

"What, Doctor? Oh what?" Asked Rory.

"because he was shot in 2161."
